In this market every person seems to follow his own agenda, and the proposal by Cobra seem to fit perfectly in that category. In order to take things to the next level, the easiest way to cause confusion is to ddos the site Cobra is managing and has direct access to. It would then look like he took it down or messed with it, while in reality it was done by someone else. I probably don't need to point people here at how easy it is to rent a ddos attack, and how cheap it is to keep it running for a few hours. I wouldn't worry much about this and especially not about the proposal....
This was my initial thought. I very much doubt that Cobra would take down Bitcoin.org intentionally to try and push his proposal through as this would of tarnished his reputation if found out to be true. AFAIK it was only down for a few hours at most, so either it was coincidental that it went down at the time of this drama, or it was indeed a ddos.
